A collaborative workspace app in Microsoft 365 designed to help teams co-create, stay organized, and work together in real time across apps and devices.
Welcome to the Microsoft Q&A forum.
Normally, when you add /github to Microsoft Loop, the system displays a dialog box with the “Proceed” option, as shown in the illustration below.
However, based on the image you provided and the results from the test environment that I performed, it appears that this dialog does not appear or is interrupted at the Proceed step, which prevents the setup process from continuing.
In this case, I recommend that you create a support ticket with Microsoft Technical Support so the issue can be reviewed and analyzed in more detail.
How to create a support ticket
Note: The steps below require a Global Administrator account. If you do not have this permission, please contact your organization’s IT department for assistance.
Step 1: Go to admin.microsoft.com
Step 2: Select Help & Support
Step 3: Enter the ticket title, for example:
Request assistance to investigate Microsoft Loop
Step 4: Select Contact Support
Step 5: Choose your preferred contact method (chat or email)
After the ticket is submitted and assigned to a support agent, Microsoft will proactively contact you to provide assistance.
Additional note: If you submit the ticket over the weekend, the support agent may contact you at the beginning of the next business week.
If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
